THE CELL 91 



of the special knowledge and skill of building those struc- 

 tures from whence they came. The fact that the centro- 

 some, who takes charge of the act of division, causes such 

 division to be exactly equal, tends to show a definite pur- 

 pose to divide the specifically skilled working force 

 equally. How this force of individuals is again able to 

 grow and increase in the cell to its full number and size, 

 the microscope is not yet powerful enough to disclose to 

 us. However, we can clearly see that it does again in- 

 crease and grow to its original number and size. 



In the act of fertilization where the male cell prepares 

 to meet the female cell, it is clear that each one knows 

 what the other is going to do and acts accordingly. The 

 female cell must know that the male cell will bring a cen- 

 trosome or general manager and the male cell must know 

 where to look for the female and also have some idea what 

 she will have and what she looks like. They must have 

 the faculty of memory, skill and intelligence to do these 

 things. Every act connected with this performance of 

 the male and female cells of preparing for and meeting in 

 the womb, is an intelligent act requiring judgment and 

 will, which must be based on memory. We do not know 

 how the cells in our brain can remember past experiences, 

 but we know it to be a fact. We know every cell in our 

 body including our muscles must also be possessed of 

 this faculty of memory, just as the cells composing our 

 nerves and brain are, if not we could learn nothing from 

 practice nor form a habit. Habit is based on the mem- 

 ory of the cells of that part of the body trained or prac- 

 tising. By repetition the acts are fixed in the memory of 

 the cells in the muscles that take part in the act, and fin- 

 ally they are remembered and then we call them habit. 



We have seen that the cell is an individual again com- 

 posed of individuals called granules; that these granules,
